Interface Summary

FilterContent<KeyType,ValueType>

A wrapper for cache entry objects which is passed to each ContinuousQueryFilter associated with a continuous query.

Class Summary

AbstractCQFilter<KeyType,ValueType,AttributeType,MatchType>	This is an abstract class which all continuous query filters must extend.
AndFilter	This filter returns true if and only if all its child filters are true.
BinaryLogicalFilter	This is a base class used for binary logic operations.
CompareFilter<KeyType,ValueType,AttributeType,MatchType>	This is a base class for filters comparing an attribute with a scalar.
EQFilter<AttributeType,MatchType>	This class checks if an attribute is equal to another object.
FalseFilter	This Filter always returns FALSE
GTEFilter<AttributeType,MatchType>	This checks if an attribute is greater than or equals to a scalar.
GTFilter<AttributeType,MatchType>	This checks if an attribute is greater than a scalar.
IsNotNullFilter	This filter checks if the attribute to be compared is not null.
IsNullFilter	This filter checks if an attribute is null.
LTEFilter<AttributeType,MatchType>	This checks if an attribute is less than or equals to a scalar.
LTFilter<AttributeType,MatchType>	This checks if an attribute is less than a scalar.
MatchFilter	This class checks if an attribute matches a regular expression pattern.
NEQFilter<AttributeType,MatchType>	This checks if an attribute does not equal a scalar.
NotFilter	This class negates the result of a ContinuousQueryFilter.
NotMatchFilter	This filter passes if the attribute does not match a provided regular expression pattern.
OrFilter	This filter passes if any child filter is true.
TrueFilter	This filter always passes.

These are the Filter implementations which are used to build continuous query definitions. An extensible abstract implementation AbstractCQFilter is also provided so that custom filters can be created.
